Electrospun drug‐loaded scaffolds for nervous system repair

Simon C. Kellaway, Mathilde M. Ullrich, Karolina Dziemidowicz

Wiley Interdisciplinary Reviews: Nanomedicine and Nanobiotechnology > 16 > 3 > n/a - n/a

Nervous system injuries, encompassing peripheral nerve injury (PNI), spinal cord injury (SCI), and traumatic brain injury (TBI), present significant challenges to patients' wellbeing. Traditional treatment approaches have limitations in addressing the complexity of neural tissue regeneration and require innovative solutions. Among emerging strategies, implantable materials, particularly electrospun...

Differential effects of visually induced analgesia and attention depending on the pain stimulation site

Larissa Cordier, Eva M. Ullrich, Stephan Herpertz, Walter Zieglgänsberger, more

European Journal of Pain > 25 > 2 > 375 - 384

Background The term ‘visually induced analgesia’ describes a reduced pain perception induced by watching the painful body part as opposed to watching a neutral object. In chronic back pain patients, experimental pain, movement‐induced pain and habitual pain can be reduced with visual feedback. Visual feedback can also enhance the effects of both massage treatment and manual therapy. The impact of...

Dark photon search in the mass range between 1.5 and 3.4 GeV/c2

M. Ablikim, M.N. Achasov, X.C. Ai, O. Albayrak, more

Physics Letters B > 2017 > 774 > C > 252-257

Using a data set of 2.93 fb⁻¹ taken at a center-of-mass energy s=3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine the initial state radiation reactions e+e−→e+e−γISR and e+e−→μ+μ−γISR for this search, where the dark photon would appear as an enhancement in the invariant mass distribution of the leptonic...

Reynolds stress modelling of wake interference of two cylinders in tandem: Conventional vs. eddy-resolving closure

R. Maduta, M. Ullrich, S. Jakirlic

International Journal of Heat and Fluid Flow > 2017 > 67 > PB > 139-148

A differential, near-wall Reynolds stress model (RSM) employed in Unsteady RANS (Reynolds-Averaged Navier–Stokes) framework, coupled with the equation governing the inverse turbulent time scale relying on the so-called 'homogeneous dissipation' rate (ωh=ɛh/k), was applied to two in-line tandem-cylinder flow configurations. The configurations differ with respect to the distance between cylinders, with...

Physics Letters B > 2016 > 761 > C > 98-103

Using a data set of 2.93 fb⁻¹ taken at a center-of-mass energy of s=3.773 GeV with the BESIII detector at the BEPCII collider, we measure the process e+e−→J/ψγ→μ+μ−γ and determine the product of the branching fraction and the electronic width Bμμ⋅Γee=(333.4±2.5stat±4.4sys) eV. Using the earlier-published BESIII result for Bμμ=(5.973±0.007stat±0.037sys)%, we derive the J/ψ electronic width Γee=(5.58±0...

Study of doubly strange systems using stored antiprotons

B. Singh, W. Erni, B. Krusche, M. Steinacher, more

Nuclear Physics A > 2016 > 954 > C > 323-340

Bound nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena. Stored antiprotons beams in the GeV range represent an unparalleled factory for various hyperon–antihyperon pairs. Their outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of systems which contain...

By analyzing a data set of 2.92 fb−1 of e+e− collision data taken at s=3.773 GeV and 106.41×106 ψ(3686) decays taken at s=3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770)→γχc0 to be B(ψ(3770)→γχc0)=(6.88±0.28±0.67)×10−3 and Γ[ψ(3770)→γχc0]=(187±8±19) keV, respectively. These are the most precise measurements to date.

We extract the e+e−→π+π− cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb−1 taken at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider is used.

M. Ablikim, M.N. Achasov, X.C. Ai, O. Albayrak, more

Physics Letters B > 2015 > 750 > C > 466-474

We study Ds+ decays to final states involving the η′ with a 482 pb−1 data sample collected at s=4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions B(Ds+→η′X)=(8.8±1.8±0.5)% and B(Ds+→η′ρ+)=(5.8±1.4±0.4)% where the first uncertainty is statistical and the second is systematic. In addition, we estimate an upper limit on the non-resonant branching ratio B(Ds+→η′π+π0)<5...

An improved limit for Γee of X(3872) and Γee measurement of ψ(3686)

M. Ablikim, M.N. Achasov, X.C. Ai, O. Albayrak, more

Physics Letters B > 2015 > 749 > C > 414-420

Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e−→γISRX(3872)→γISRπ+π−J/ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872) via single photon e+e− annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We...

Worldviews on Evidence‐Based Nursing > 12 > 4 > 208 - 216

BackgroundAlthough the literature has noted the positive effects of facilitation in implementation research, little is known about what facilitators do or how they increase adoption of a program. The purpose of this study was to understand internal facilitation activities in implementing a national safe patient handling program from the perspective of facility coordinators who implemented the program...

The P̄ANDA Collaboration, B. P. Singh, W. Erni, I. Keshelashvili, more

The European Physical Journal A > 2015 > 51 > 8 > 1-19

Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address the possibility of accessing nucleon-to-pion (πN) TDAs from $$\bar pp \to e^ + e^ - \pi ^0 $$ reaction with the future P̄ANDA detector at the FAIR...
